P200 Malossi 210. Tech Tips and secrets.Setting up a malossi
Cylinder on a P200 Vespa is not just a matter of 'one off one on' and away we
go, contrary to popular belief! Weve ridden a few of these incorrectly assembled
engines and there's no wonder why there are so many Scooterists who speak poorly
of the Malossi 210 conversion. We'll show you how city Skoots does it.It's our
specialty. In standard guise they aint too interesting, but try upping the snort
by over 100% and look out. This is a typical recipie for a 25hp (rear wheel)
engine unit that when tuned correctly is extremely fast & reliable while
still being tractable enough for everyday riding. If youre considering upgrading
then let city Skoots do the job. You wont be disappointed! (usually
speechless).Hmmm, where did all these fast TS1's go that we keep hearing about?

Setting up the engine case is
extremely important.We always
Devconthe existing unused transferr entriesthen start from
scratch. This helps raisethe case compression also while
providinga smooth feed to the transfer ports.Benefitsare 2 fold.
Dont make the mistake and usethe supplied base gasket as a template.
Itmust be done by feel and individually matchingeach case half to
the Barrel. The rear port is a weird shape. It can either be filled
and recutor reshaped completely. Here we have enlargenedit while
making the corresponding mods to theCylinder. It benefits low to mid
power delivery.It's a lot of work but the results speak for
themselves.

Opting for Reed valve induction on
most conversions requires
completelyaltering the case feed. There is no longerthe necessity
for the valve plane used inthe original rotary induction. There's a
fineline between getting the right shape and avoidingremoving too
much volume. Experience shows thisis how it ends up looking. Notice
the amount oftime that has been put into matching the manifoldit
is rare to see this kind of preparationperformed, but the results in
performance give adefinite payoff

The Malossi Reed Valve and 30mm
Carb provide outstanding results
whenmatched and modified correctly. Again,hours of work and
detail. The high qualityfinish is incidental of high quality
workmanship.We also use other aftermarket Reed Valve
setupsmarketed by some of the main UK tuning companies.While these
run larger Reed cages (and suit biggerCarbs) and improve top end power
to a degree, wehave found that the increased case volume leadsto a
significant loss in mid range punch
